This isn’t a metaphor; it’s brain biology. Scientists have found that in substance addiction, environmental cues such as being in a place where drugs are taken or meeting another person who takes drugs cause sharp surges of dopamine in crucial reward and habit regions of the brain, specifically, the nucleus accumbens and dorsal striatum. This triggers cravings in anticipation of experiencing pleasure and relief through intoxication. Recent studies show that similarly, cues such as experiencing or being reminded of a perceived wrong or injustice — a grievance — activate these same reward and habit regions of the brain, triggering cravings in anticipation of experiencing pleasure and relief through retaliation. To be clear, the retaliation doesn’t need to be physically violent—an unkind word, or tweet, can also be very gratifying.
